Eastern Provinces of Saudi Arabia Storm water Drainage

Description

The eastern province cities Dammam, Qatif, Saihat and Khobar form a densely populated region with approx. 2 million inhabitants. Currently, only 10% of the area is served by stormwater networks. In this region the high subsurface water level causes many problems for civil structures (roads and buildings). The aim of the study was to analyse the existing situation in order to find present and future orientated strategies to solve these problems. After analysing the existing situation, recommendations in the fields of stormwater drainage, stormwater treatment, disposal points and lowering the subsurface water level were given. The required steps to find cost optimized solu-tions were developed and defined. To prevent the construction of drainage pipes covering the long distance from the western region to the coast, a new drainage system was proposed including: artificial evaporation lakes in some districts in the western part of the project area. TECHNICAL DATA – Project area: approx. 1,900 km2 – Number of proposed artificial lakes: 4 – Number of pump stations: 34 – Capacity of pump stations: 500 to 20,000 l/s – Type of pump stations: — Submersible pumps — Archimedian screw pumps — Vertical shaft pumps
